In regions of the United States and Mexico that are prone to hurricanes, aggressive spiders are evolving to survive and ride out the storm.When hurricanes rage along the Gulf of Mexico or charge up the East Coast, they can reshape an entire habitat in a short time. The winds destroy trees and spread debris for miles, putting new pressure on the creatures living in these environments.But how do creatures adapt when their habitats are so disturbed? Researchers looked at Anelosimus studiosus spiders that live in storm-prone areas along the coast to see how they changed. Their study was published Monday in the journal Nature Ecology and Evolution.These weather systems are called "black swan events": a surprising event with a major impact that is explained with the benefit of hindsight. They don't offer much lead time, so the researchers had to scramble to study the spider colonies before and after projected storms.The team monitored Subtropical Storm Alberto and Hurricanes Florence and Michael during the 2018 hurricane season. They tried to anticipate the systems' trajectories and study areas that included 240 female spider colonies, comparing them with areas where spider colonies were unaffected by such storms.The researchers returned to the sites hit by the storms 48 hours later. About 75% of the colonies survived the initial storm strikes."It is tremendously important to understand the environmental impacts of these 'black swan' weather events on evolution and natural selection," said Jonathan Pruitt, lead study author, evolutionary biologist and Canada 150 Chair in McMaster University's Department of Psychology, Neuroscience & Behaviour. "As sea levels rise, the incidence of tropical storms will only increase. Now more than ever we need to contend with what the ecological and evolutionary impacts of these storms will be for non-human animals."The A. studiosis spider species has two main personality traits that are inherited: docile and aggressive.Aggressiveness can be determined based on their speed, attackers pursuing prey, cannibalizing male spiders as well as eggs and their vulnerability to the invasion of predatory spiders.On the one hand, aggressive colonies are better at gathering resources in times of scarcity. But when deprived of food or subjected to overheating, aggressive colonies can also suffer from infighting."Tropical cyclones likely impact both of these stressors by altering the numbers of flying prey and increasing sun exposure from a more open canopy layer," Pruitt said. "Aggressiveness is passed down through generations in these colonies, from parent to daughter, and is a major factor in their survival and ability to reproduce."The researchers determined that after a storm passed, the colonies that aggressively pursued food and resources were able to produce more egg cases. The spiderlings also had a better chance of surviving into early winter.In areas that weren't hit by storms, docile colonies thrived.These findings were consistent even as the storms varied in duration, intensity and size. The researchers believe this shows that extreme events can shape animal behaviors. They would like to conduct more long-term studies to learn whether this is the case. 3250

If you recently waited in a crowded doctor’s office or you’ve called to make an appointment and were told the next slot available is in several weeks or months, you’ve already experienced the effects of America’s doctor shortage.It's become more common for doctors, like New Jersey urologist Dr. Thomas Mueller, to practice with a packed patient schedule."The amount of patients we see is borderline insane," Mueller says.“I'll be the first one to say I don’t think it’s the best thing in the world," he says. "The things that I do to combat it is I just invest a lot of time beforehand.”Mueller and the team of physicians at Delaware Valley Urology each see upward of 50-60 patients a day.And that’s still not enough. "With the baby boomers becoming, you know, in their 70s, there are a lot of people to be seen," the doctor says. "The overall structure of medicine, at least as far as training is concerned, they’ve never really increased the enrollment in medical schools.”Unless significant steps are taken, the Association of American Medical Colleges predicts the shortage is only going to get worse.“I think I am at my max (amount of patients)," Mueller says. "I don’t think I can do a whole lot more."To help with the issue, legislators are proposing several bills that would raise grant money for more medical residency slots, and to make it easier for foreign doctors to practice in the U.S.In addition, medical schools have increased scholarships. Some have even created specific residency slots for those willing to practice in rural areas.“There are folks who think that there is a shortage," says Dr. Bob Motley. "I think we have as much of a problem with the maldistribution.”Motley runs Thomas Jefferson University's Physician Shortage Area Program. “We have about 50% of all physicians in Pennsylvania that are actually clustered in three counties," he says. "But 75% of Pennsylvanians actually live outside those areas.”Motley’s program has graduated roughly 400 doctors, and almost 80 percent are now practicing in rural communities hit the hardest by this doctor shortage."There's a lot to be learned in health care and we definitely have not figured it out," Mueller says. "It’s not a broken system by any stretch of the imagination but it’s things that are ever changing. And I think everyone is striving to make it better.”In addition to seeing 50 to 60 patients a day, Mueller also trains residents to handle the patient load as it is now."It's not for the faint of heart," he says. "But at the same time we do it because we love it.” 2571

IndyCar and NASCAR will both race this weekend without spectators over fears of the COVID-19 pandemic. IndyCar is scheduled to open its season Sunday on the streets of St. Petersburg, Florida. Only essential personnel will be permitted to attend. Competitors will also undergo a questionnaire for health screening before entry. NASCAR will race this week at Atlanta and next week at Homestead-Miami Speedway under similar restrictions. The NHRA has canceled much of the GatorNationals and IMSA rescheduled the 12 Hours of Sebring in Florida. 554

Iran's Foreign Minster Javad Zarif said that his nation does not "seek escalation or war" following an attack on a pair of Iraqi bases that house US troops early Wednesday morning. Iraqi security officials told CNN that no casualties were reported following the attacks on Al-Asad Airbase and Irbil Airbase in Iraq, where United States troops are stationed. "Iran took & concluded proportionate measures in self-defense under Article 51 of UN Charter targeting base from which cowardly armed attack against our citizens & senior officials were launched," Zarif said. "We do not seek escalation or war, but will defend ourselves against any aggression."Hours after Zarif's statement, Iranian State TV reported that Iran will tell the UN Security Council it will not seek to go to war with the U.S.More than a dozen missiles struck two airbases in Iraq that houses U.S. troops early on Wednesday morning, the Pentagon confirmed.While Zarif said that Iran does not seek to escalate tensions in the Middle East, the Islamic Revolutionary Guard Corps (IRGC) said through Iran State TV that the United States would face a broader and stronger response if the US responded to the Iranian missile attack.Zarif has been vocal in his criticism of the U.S., especially President Donald Trump, after the U.S. launched an attack that killed Iranian General Qasem Soleimani last week. "The US' act of international terrorism, targeting & assassinating General Soleimani—THE most effective force fighting Daesh (ISIS), Al Nusrah, Al Qaeda et al—is extremely dangerous & a foolish escalation. The US bears responsibility for all consequences of its rogue adventurism," Zarif previously said. 1703

Kentucky and Nevada both announced the first coronavirus-related deaths in their state on Monday.Kentucky Gov. Andy Beshear said Monday morning that a 66-year-old man from Bourbon County had died. The governor cited "numerous factors" with the man's death in addition to COIVD-19.The total number of cases of COVID-19 in the commonwealth remained at 21. More than 3,000 people are confirmed to have contracted the virus in the United States, and at least 69 people have died.Kentucky is the 12th state to announce a fatality linked to the coronavirus.The Pentagon is currently holding a press briefing. See the video below."This is our duty as Kentuckians, this is our patriotic duty," he said of protecting one another through proper hygiene and social distancing. They also were pushing new hashtags for use on social media: #TeamKentucky #TogetherKY."I know that there is anxiety out there" Beshear said. "I know a lot of it is spread through social media."Also on Monday, the Southern Nevada Health District said a man in his 60s with underlying health issues had died of COVID-19.“We must continue to emphasize how important it is to protect those who are most vulnerable to the impacts of the virus and urge our community to support the public health measures and recommendations that are in place,” said Dr. Fermin Leguen, Acting Chief Health Officer of the Southern Nevada Health District..The announcements came the day after Oregon announced its first death linked to the coronavirus pandemic.
